Overview   Experience   Media/Events   Activities/Honors

Steve knows that clients’ lives – and livelihoods – can be upended or even destroyed when tax trouble arises. For more than 30 years, Steve has made it is his personal mission to help business owners and individual clients successfully resolve tax issues and go on with their lives. With extensive knowledge of tax law, a desire for swift and vigorous defense, and decades of experience with tax authorities and in the courts, he has unusually perceptive judgment in assessing the best way forward, and the right resources to achieve resolution.

Steve started Moskowitz LLP because he saw that while big corporations were consistently navigating the tax code to their advantage, smaller businesses and individuals were not. With prior experience as a CPA at a national accounting firm, and with extensive experience in the corporate world, Steve knew he could help smaller businesses and individuals by applying what he knew, and wanted to make the critical difference in businesses and individual lives that protected them from the powerful government and enabled them to keep and enjoy the fruits of a lifetime of work that otherwise could be taken away from clients by the government in just one action.

Today - together with a full team of tax attorneys, CPAs, enrolled agents and other professional staff - Moskowitz LLP helps business and individual clients across the country and overseas to resolve a wide variety of tax matters. The Moskowitz LLP team also creates strategies to utilize the tax code and relevant treaties to clients’ benefit, and provides ongoing tax support and tax return preparation.

Steve understands that clients need high quality representation but do not have unlimited budgets, and that cost predictability is important. Unlike most firms, Moskowitz LLP clients pay a flat fee and are not subject to hourly rates.

Steve has experience resolving a broad range of tax issues for both business owners and individuals, such as:

  • Tax audit proceedings and related matters
  • Defense in tax-related civil and criminal proceedings
  • Foreign asset and income tax defense
  • Foreign tax and asset planning, including treaty utilization
  • Tax planning and dispute resolution
  • Defense of investors in and promoters of off-shore tax shelters
  • Domestic tax planning and representation
  • Payroll and sales tax disputes
  • Tax opinions and appeals
  • Securities & Exchange Commission and Federal Trade Commission matters
  • Negotiations for businesses and individuals who cannot pay their taxes

Steve has represented clients in front of numerous administrative agencies as well as in state and federal courts, such as the following:

  • Internal Revenue Service (including Civil and Criminal Investigative Divisions)
  • State and local taxing authorities
  • Department of Justice
  • United States Tax Court
  • U.S. District Courts

Prior to founding Moskowitz LLP, Steve practiced as a CPA in New York City. In addition to extensive practical experience as a tax attorney, Steve also has an MBA in accounting, an advanced law degree in tax (LL.M), and an undergraduate degree in accounting. He has served as an adjunct professor of law, tax, and accounting in law school, graduate school, and undergraduate universities.
